RENDERING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 696,506, dated April1, 1902. Application filed June 12, 1901. Serial No. 64,314. (No model.)

To (0 whom it may concern:

Be it known that I, JOHN CHARLES WIL- LIAM STANLEY, asubject of the Kingof England, residing at London, England, have invented certain new anduseful Improvements in Steaming-Kettles for Fish, Meat, 850., of whichthe following is a specification.

This invention relates to steaming-kettles for use in treating fish,meats, slaughterhouse offal, &c., for the purpose of extractingoleaginous matter therefrom.

The object of the invention is to improve devices of this character,whereby superior results will be obtained, especially in the quality ofthe oleaginous matter extracted.

The invention and the advantages arising therefrom will be fullydescribed hereinafter, reference being had to the accompanying drawings,in which-- Figure 1 is a side elevation of a steamingkettle constructedin accordance with myinvention. Fig. 2 is an end view. Fig. 3 is a plan,the cover being removed; and Fig. 4is a section on the line 4: 1 of Fig.1, the feedhopper and the exhaust being omitted.

The outer shell or casingAis substantially U-shaped in cross-section, isclosed at both ends, and provided with a cover B, which is detachablysecured to the shell in any desired manner to form practically asteamtight joint. sectionally U-shaped plate 0 is supported to leave aspace or chamber D between it and the bottom of the casing, and thisplate extends from end to end of the casing. A vertical partition Eextends between the plate D and the cover from one end thereof to nearlythe other end, thereby forming two parallel compartments 10 and l1,whichoommunicate at one end of the casing A.

Supported upon the plate 0 are two perforated steam-pipes 12 and 13, oneon each side of the partition E, and these pipes are connected by aperforated coupling 1% at their inner ends at the end of the partitionand form practically a continuous pipe, and a steam-supply pipe 15 isconnected to'the end of one of the pipes, and the adjacent end of theother pipe will be closed.

Angle-bars 16 are secured to the plate 0 parallel to the partition E andhold the steam-pipes in position, and from the upper Within the casing Aa cross-' edges of these angle-bars perforated curved.

plates 17 extend to the partition E, to which they are secured. Whensteam is admitted through the pipe 15 to the pipes 13 and 12, it willissue from the perforations in the pipes 13 and 12 and pass through theperforated plates 17 into the compartments 10 and 11 andcook thematerial being treated. The plate 0 is perforated, and as the cookingprogresses the oleaginous matter will be extracted from the materialunder treatment and, with the water of condensation and such otherliquid as may be extracted from the material under treatment, will dripthrough the perforations in the plate 0 into the chamber D, from whichit may be drained off through pipes d (Z into a receptacle. (Not shown.)A feed-hopper Fis supported upon one end of the casing A to deliver thematerial'to'the end of one compartmentin this case the compartment10-and is provided with a removable cover f. An exhaust-pipe G leadsfrom the casing to a condenser. (Not shown.) Some means must be providedtomove the material to be treated through the compartments 10 and 11,and in such movement the material should not be mashed 0r pulped, as itwould then form a compact mass and render it diliicult to separate theoleaginous matter. In order to move the material continuously and at thesame time keep it broken up, I preferably use the following mechanism:Extending longitudinally through each compartment 10 and 11 is a shaftK, one end of which is positively driven by gearing 20, which is drivenby a belt-pulley 21. The other end of the positively-driven shaftisprovided with a gear 22, which meshes with a similar gear 23 on theother shaft, and the two shafts are thus driven, but in reversedirections. To each shaft a spirally-twisted blade is is attached bymeans of a series of brackets 24., secured at intervals to the shaftsand blades. The blades surround the shafts, but do not touch them, thusleaving an annular space between the inner edge of the blade and theshaft, which is obstructed at intervals by the brackets 2a. Much of thematerial as it is moved along will pass along this annular space, andthe brackets will constantly break it up and prevent it from forming acompact mass, as would be the case if the blade engaged the shaft, andthe material could only follow the spiral passage formed by the blade.Of course as the cooking of the material proceeds it will become broken,up more or less, but it will not compact into a solid mass, andconsequently the oleaginous matter will have full opportunity toseparate from the material. The conveyerin the compartment 10 will movethe material to the end of the partition E, and then the conveyer in thecompartment 11 will move it along in the opposite direction, and thecooked material will be discharged through an outlet 25 at the end ofthis compartment adjacent the feedhopper.

By using free steam to cook the material it will not be burned and theoleaginous matter will be of a much better color, because it will not besubjected to continuous cooking, but can escape as soon as it is freedfrom the material being treated. By draining the oleaginous matter offas soon as freed from the material the usual subsequent step of pressingthe cooked material to express the oleaginous matter is dispensed with,and, furthermore, the separation is more complete.

I do not limit myself to the specific devices illustrated to move thematerial through the compartments and at the same time prevent it fromforming a compact mass, as other devices might be employed to accomplishthis result; nor do I limit myself to the other precise details ofconstruction illustrated and described; but,

. Having described an apparatus adapted to carry out my invention, Iclaim 1. In an apparatus for extracting oleaginous matter from fish,meats, &c., the combination of a closed vessel, a perforated plateextending transversely thereof above the bottom, a vertical partitionextending upwardly from the perforated plate to form two compartmentsabove the said plate communicating at one end of the partition, aperforated steampipe on each side of the partition to discharge freesteam into the respective compartments, means to feed the material to betreated to the end of one compartment, means to move it through thecompartments, and means to drain off the oleaginous matter from thespace between the perforated plate and the bottom of the vessel,substantially as set forth.

2. In an apparatus for extracting oleaginous matter from fish, meats,85c. the combination of a closed vessel, a perforated plate extendingtransversely thereof above the bottom, a vertical partition extendingupwardly from the perforated plate to form two compartments above thesaid plate communicating at one end of the partition, a perforatedsteampipe on each side of the partition to discharge free steam into therespective compartments, means to feed the material to be treated to theend of one compartment, means to move it through the compartments andmaintain it in a broken-up condition, and means to drain off theoleaginous matter from the space between the perforated plate and thebottom of the vessel, substantially as set forth.

3. In an apparatus for extracting oleaginous matter from fish, meats,&c., the combination of a closed vessel, a perforated plate extendingtransversely thereof above the bottom, a vertical partition extendingupwardly from the perforated plate to form two compartments above thesaid plate communicating at one end of the partition, a perforatedsteampipe on each side of the partition to discharge free steam into therespective compartments, means to feed the material to be treated to theend of one compartment, means to move it through the compartment, meansto discharge the cooked material, an exhaust-pipe leading from theclosed vessel, and means to drain off the oleaginous matter from thespace between the perforated plate and the bottom of the vessel,substantially as set forth.

4:. In an apparatus for extracting oleaginous matter from fish, meat,850., the combination of a closed vessel, a perforated plate extendingtransversely thereof above the bottom, a Vertical partition extendingupwardly from the said plate to form two compartments above the platecommunicating at one end, means to admit free steam to each compartment,means to feed the material to be treated to the end of one compartment,and means to move it through the compartments and maintain it in abroken-up condition, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
